For an 11y this is really impressive and you should continue doing this.
No matter what the final rating will be, there are some things nobody can take away from you:
You not only started to make a game, you completed and released one. That is not a small feat.
Unlike other entries this one just works and does not have obvious bugs.
Last but not least: We all started small at some point but what matters is how (and if) you finish.
Keep it up!
